Hmm, I get the registration screen but I didn't try to register
I am thinking that it is picking up the IP address and denying for that reason.
We should fix it where more than 1 per IP can register. I could get my grandson to register. He would not suffer any kind of problems so I will not mention it until it's fixed.
To get any real growth we will need to connect to the social networking sites like Facebook and twitter. You can easily (I think) include a button at the bottom of every post to share on Facebook or tweet a link to your post.
It would be interesting to have more viewpoints and some newbies to kick around. :)
